Remarks

CPUE can be used as a measure of the economic efficiency of a type of gear, but normally it is used as an index of abundance, i.e. a proportional change in CPUE is hoped to represent the same proportional change in abundance. Nominal CPUE is simply the measure of CPUE from the fishery. However, it is known that there are many factors (including economics, geographical distributions) which may affect CPUE but do not represent changes in abundance. Therefore, CPUEs are often "standardized" using a variety of statistical techniques to remove the effect of those factors which are known not to be related to abundance. Thus, using the standardized CPUE will be more appropriate for an index of abundance. Most assessment analyses (production models, virtual population analyses) use the index of abundance data to fit to calibrate (tune) the models.

Definition

The amount of catch that is taken per unit of fishing effort (e.g., number of fish per longline hook-months). Nominal CPUE is often used as a measure of the economic efficiency of a type of gear. Standardized CPUE is normally used as an abundance index for "tuning" assessment models.

Definition

The quantity of fish caught (in number or in weight) with one standard unit of fishing effort; e.g. number of fish taken per 1000 hooks per day or weight of fish, in tons, taken per hour of trawling. CPUE is often considered an index of fish biomass (or abundance). Sometimes referred to as catch rate. CPUE may be used as a measure of economic efficiency of fishing as well as an index of fish abundance. ). Also called: catch per effort, fishing success, availability.

Observaciones

La CPUE puede utilizarse como medida de la eficiencia económica de un tipo de arte, pero normalmente se utiliza como índice de abundancia, es decir, se espera que una variación proporcional en la CPUE represente la misma variación proporcional en la abundancia. La CPUE nominal es simplemente la medida de la CPUE de la pesquería. Sin embargo, se sabe que existen muchos factores (incluidos factores económicos, distribuciones geográficas) que pueden afectar a la CPUE pero que no representan variaciones de abundancia. Por tanto, las CPUE suelen "normalizarse" utilizando varias técnicas estadísticas para eliminar los efectos de dichos factores que se sabe que no están relacionados con la abundancia. Por ello, la utilización de la CPUE normalizada resultará más apropiada para un índice de abundancia. La mayoría de los análisis de evaluación (modelos de producción, análisis de población virtual) utilizan el índice de datos de abundancia para calibrar (ajustar) los modelos.

Définition

Volume de la capture prise par unité d'engin de pêche. Par exemple, le nombre de poissons pris par hameçon de palangre-mois est une façon d'exprimer la CPUE.

Observations

Elle peut servir à mesurer le rendement économique d'un type d'engin, mais elle est normalement utilisée comme indice de l'abondance, c'est-à-dire que l'on espère qu'une modification proportionnelle de la CPUE représente la même modification proportionnelle de l'abondance. La CPUE nominale est simplement la mesure de la CPUE fournie par la pêcherie. On sait toutefois que de nombreux facteurs (entre autres économiques, géographiques) peuvent influer sur la CPUE, mais ne représentent pas des variations de l'abondance. C'est pourquoi les valeurs de la CPUE sont souvent "normalisées" au moyen de diverses techniques statistiques pour éliminer l'effet de facteurs dont on sait qu'ils n'ont pas trait à l'abondance. La CPUE normalisée sera donc une mesure plus appropriée de l'indice d'abondance. La plupart des analyses d'évaluation (modèles de production, analyses de la population virtuelle) utilise les données de l'indice d'abondance pour calibrer les modèles.
